For longer than science fiction has even existed, humans have been fascinated with (and terrified by) the prospect of space rocks falling to Earth. But why?
There is one obvious explanation: Asteroids have fallen to Earth many times before, sometimes with devastating consequences. ( RIP, dinosaurs .) But at present, there is no imminent threat of any space rock hitting Earth and causing harm.
An asteroid bigger than Philly's City Hall will be 'near' Earth on Saturday, but not to worry
The oblong asteroid, dubbed 2004 UE, is attracting attention because of its size: more than 1,000 feet long and 460 feet wide, give or take. For perspective, that's bigger than two Philadelphia City Halls, one piled on top of the other.
Should anything that size ever come truly near Earth—and there's no sign that will occur this century—NASA is getting ready.
To Save Earth, NASA Is Testing Hitting An Asteroid With A Spacecraft
Andy Rivkin remembers going to the arcade in the early 1980s to play the iconic video game "Asteroids.
The launch window for NASA's Double Asteroid Redirection Test (DART) mission opens next week. DART is an experiment to see if by crashing a spacecraft directly into an asteroid, the asteroid can be nudged off its trajectory.
Testing mini-radar to peer inside asteroid
CubeSats are mini-satellites built up from standardized 10-cm boxes. Juventas is a '6-unit' CubeSat, measuring 10x20x30 cm, while its quartet of radar antennas measure 1.5 m long each.
The test campaign is taking place inside the "Hybrid European Radio Frequency and Antenna Test Zone' or Hertz chamber at ESA's European Space Research and Technology Centre (ESTEC) in the Netherlands. However testing here only became feasible after a skillful upgrade.
Redwire to Provide Technology for NASA's Asteroid Redirection Test Mission - MarketWatch
Redwire Corp. will provide navigation components and roll-out solar array technology for the National Aeronautics and Space Administration's Double Asteroid Redirection Test mission.
The DART mission is a test of "technologies for preventing an impact of Earth by a hazardous asteroid," according to NASA's website. It will be "the first demonstration of the kinetic impactor technique to change the motion of an asteroid in space."
EXCLUSIVE: Our mission the most extensive study of main asteroid belt, says UAE space agency
UAE space mission: The United Arab Emirates last year launched the Hope Probe to Mars as its first space exploration mission.
The mission will make a journey of 3.6 billion kilometers across a period of five years, during which time it will first go to Venus for a flyby while collecting important data from the planet.
NASA warns huge asteroid is heading towards Earth in December | Impartial Reporter
The “potentially hazardous” space rock called 4660 Nereus is set to make a close pass of the earth next month.
But should humanity be worried - and how does Nasa know this asteroid could be hazardous to our planet?
On 11 December 2021, the 330m-long asteroid 4660 Nereus is set to whistle past the earth at a speed of 6.58 kilometres-per-second at a distance of 2.4 million miles.
Interstellar object 'Oumuamua is not an iceberg made out of pure nitrogen, scientists say | Daily
The scientific community has long debated what the interstellar object 'Oumuamua is, but one group of researchers believes it is not a nitrogen iceberg, according to a new study.
A team of researchers, including the Harvard astrophysicist who suggested 'Oumuamua was a 'lightsail' sent from another civilization, note there is not enough nitrogen in the known universe to make an object that size.
Starship Troopers: Was The Buenos Aires Asteroid Attack A False Flag?
It should not come as a surprise to any movie lover that sci-fi fans are still scouring through and discussing the depth of Paul Verhoeven’s Starship Troopers (1997). A movie that was once derided as shallow or over pulpy has become an enduring cult classic – rightly so.
Evident as far back as the days of ancient empires all the way up to the modern stream of events, human history is chock-full of ill-intentioned governing bodies.
Earthquake warning: Simulation showed magnitude 20 'could occur': 'Would destroy
This is because the scale of an earthquake is related to the length of the fault on which it occurs: the longer the fault, the larger the earthquake.
To produce a magnitude 10.5 earthquake, there would need to be a fault line with a length of around 80,000 km.
